For those who are not familiar with International Print Day, it is “24-hour celebration without borders” for “anyone with an interest in the original communication delivery device…to join the planet’s largest conversation about print in all its forms.” International Print Day starts at 6 pm ET on October 18th (11 pm GMT, 9 am AEST) and will finish 24 hours later. Those wishing to participate on social media should use the hashtag #IPD16.
